In the type of electric toaster in which the bread is supported on abread rack adapted to be depressed to bringthe bread into toastingposition, an operatin finger piece is employed which is located at oneend of the toaster and is adapted to be depressed to actuate thetoaster. Also, a dummy finger piece is invariably provided at the otherend of the toaster which is fixed relative to the toaster case. Thesetwo finger pieces serve for carrying the toaster about. The operator,when wishing to actuate the toaster, frequently attempts to depress thesta tionary finger piece with no results. This means that the toasterprobably has to be turned 'end for end or that the depression of theproper finger piece must be made with the left hand and be comes awkwardand inconvenient. The present invention overcomes this disadvantage byproviding a mechanism by means of which the toaster may be operated bydepression of either of the finger pieces.

For the purpose of illustrating our invention, we have shown in thedrawings, an electric toaster similar to that disclosed in the patent toRobert Sardeson, #2,365,909, for Food Cooking Device issued December 26,1944. Due to the fact that certain of the mechanisms of the instanttoaster do not form any particular feature of our invention, the samehave not been fully illustrated and described in this application andreference to the said Sardeson patent is to be had for such details. I

The electric toaster illustrated comprises a frame A best shown in Figs.1 and 2. This frame carries within itself, a toaster B and at theoutside portion of the same, a timing mechanismC for timing andcontrollin the operation of the toaster. These various parts will now bedescribed in detail. I p

The frame A is best shown in Fig. 2 and consists of a lower horizontalframe member [0 constructed of sheet metal and two vertical end framemembers i i and 62 attached to the frame member ID. The frame A furtherincludes an upper horizontal frame member M which together with thelower frame iiie'mberill connects the frame members I l and I2 together.

The frame A is contained within a case D which consists of two sidemembers" f4 and I5, two end members It and H and a cap [8. The sidemembers l4 and 55 are c'on'structe'd of sheet metal and have flanges i9eiiten'ding inwardly therefrom. The cap [8' has flanges 22' turnedinwardly from the same which are bolted to the flanges H] by means ofbolts 23. The two end casemembers are constructed of plastic and haveattached to them, two supporting bars III which have ears I12 bentinwardly therefrom. These ears rest upon projections II3 formed on theend case members I6 and IT and are secured thereto by means of screwsH4. The bars I'll have formed on them flanges 2| which are secured tothe side case members I4 and I5 by means of screws 28. The .bars IIlalso have bent inwardly therefrom, lugs I which overlie the marginalportions of the frame member II] of frame A. Screws I16 hold the saidframe attached to these lugs. In this manner, the frame A is attached tothe case D and all of the operating mechanism associated therewithsupported within said case.

Toaster B is constructed in the following manner: Disposed between thetwo end frame members II and I2 are four heating elements 26. Each ofthese heating elements is constructed from two sheets of heat-resistinginsulating material 21 on which are wound heating coils 28 of resistancewire or ribbon. The sheets of insulating material 21 are supported attheir lower ends by means of clips 29 turned up from the lower framemember I0 and which are held in proper spaced relation by means ofthreaded rods 3| which extend through the same. Nuts 32 screwed on theserods engage the said sheets of insulating material and hold the same inproper relation. These heating elements provide spaces 33 between pairsthereof which form ovens in which the bread to be toasted is inserted.The intermediate heating elements 26 are also separated to form a space34 therebetween in which certain of the operating parts of the inventionare disposed. Cap I8 is constructed with openings 35 in the same whichregister with the ovens 33 and through which the bread to be toasted maybe inserted into the said ovens. The bread, on being inserted in theovens, is held away from the heating elements by means of guard wires 36disposed on each side of the openings 35 and attached to the framemembers I0 and I3.

The bread to be inserted into the ovens 33 is supported on two breadracks 3! and 38 best shown in Fig. 1. These bread racks consist of bars39 extending throughout the extent of the frame A which are providedwith lugs 4| which project outwardly therefrom and on which the breadrests. The bars 39 extend through slots 42 in the end frame members IIand I2 and project outwardly beyond the same. The two bars 39 of thebread racks 3! and 38 have connected to them a cross bar 43' which holdsthe said bread racks in proper spaced relation. This cross bar hasattached to it a U-shaped slider 44 which slides upon a verticallyextending rod 45. Rod 45 is mounted in two brackets 46 and 41 attachedto the end frame member II. By means of this construction, the two racksare mounted for sliding movement in a vertical direction to permit oflowering the slices of bread into the ovens 33 or ejecting the sametherefrom.

For operating the bread racks 31 and 38, two levers 48 and 49 areemployed. The lever 48 is secured to a shaft 5| which is rotatablymounted in brackets 52 secured to the end frame member II by means ofscrews 53. The lever 48 has an arm 54 which projects through a slot 55in the end member I6 of the case D and which is operable therein. Thisarm has secured to it a finger piece 56 by means of a set screw 51. Thesaid lever 48 also has an arm 58 which extends downwardly therefrom andwhich serves to op- 4 erate the bread racks 31 and 38 as will bepresently described in detail.

The lever 49 similar to the lever 48, is attached to a shaft 59. Thisshaft is mounted for rotation in the following manner: Extendingparallel to the end frame member I2 is a plate 6| which is spacedtherefrom. The plate 6|, at its uppermost portion, has a flange 62 bentinwardly therefrom which overlies an extension 63 on the upper framemember I3. A screw 64 extends through this extension and is threadedinto the flange 62. This holds the upper end of the plate 6| inposition. The lower end of the plate 6| has two legs 65 and 66 bentinwardly therefrom which extend toward the end frame member I2. Theselegs have flanges 61 extending outwardly therefrom and which overlie theend frame member I2. Screws 68 pass through said flanges and arethreaded into the end frame member I2, thus holding the lower end of theplate 6| in position with reference to the end frame member I2. Theshaft 59 is journaled in the leg 65 of plate 6| and in a bracket 69attached to the plate 6| by means of screws I I.

The lever 49 has an arm I2 which projects through a slot I3 in the endmember II of case D and which is vertically operable therein. This armhas attached to it by means of a set screw I4, a finger piece I5. Thelever 49 is formed with another arm I6 which extends upwardly therefromand which has pivotally connected to it by means of a rivet II, a linkI8. This link extends through the space 34 at the lowermost portionthereof and is connected to the arm 58 of lever 48 by means of a rivetI9. It will be noted that the arm 58 extends downwardly while the arm I6extends upwardly. This causes corresponding movement in the oppositedirection of the two levers 48 and 49. When finger piece I5 isdepressed, lever 49 is moved in a counterclockwise direction. Thiscauses movement of the lever 48 in a clockwise direction.Correspondingly, downward movement of the finger piece 56 causesdownward movement of finger piece I5.

The bread racks 31 and 3B are operated by means of a straight linemotion indicated in its entirety by the reference character 8 I. Thismotion includes a rigid arm 82 which extends through a slot 83 in theframe member II and which has a flange 84 overlying the cross bar 43which connects the two bars 48 and 49 of the bread racks 31 and 38together. Rivets 85 ex tending through these parts secure the bar 82rigidly to the bread racks. In addition to the bar 82, a floating link86 is employed. This link is pivotally connected to the bar 82 by meansof two arms 81 and 88 which are pivoted to the said arms by means ofrivets 89. Other arms 9| and 92 are pivoted to the floating link 86 bymeans of the rivets 89 and are also pivoted by means of rivets 93 tobrackets 94. These brackets have flanges 95 underlying the upper framemember I3 and are secured thereto by means of screws 98 which extendthrough said frame member and are threaded into the flanges 95. It willthus be comprehended that a straight line motion is formed for movingthe bread racks 31 and 38 whereby the said bread racks may move from theposition shown in Fig. 2 and to the position shown in Fig. 3 and viceversa.

The straight line motion 8| is operated by means of the arm 9|. For thispurpose, a lever 91 is employed which is rotatably mounted on the shaft59 carrying the lever 49. The lever 91 has pivoted to it by means of arivet 98, a link 99.

This link is, in turn, pivoted by means of a rivet IOI to the arm 9Ipreviously referred to. The arm 13- of lever 49 is adapted to operatethe lever 91 by means of a lug I02 extending outwardly from the lever 91and in the path of movement of the arm 16. It will thus be seen that bydepressing either of the finger pieces or 53 that the bread racks 31 and38 are simultaneously moved from their uppermost positions to theirlowermost positions as indicated in Figs. 2 and 3.

The finger pieces 15 and 56 are urged upwardly .by means of a torsionspring I03 best shown in Figs. 5 and 8. This spring encircles the shaft59 and has one end I94 in engagement with the plate BI. The other endI05 of this spring is hooked about an arm I03 rigidly secured to theshaft 59. The spring I03 is so tensioned that the shaft 59 is urged torotate in a clockwise direction as viewed in Fig. 2 thus urging both ofthe finger pieces 15 and 58 upwardly and also the bread racks 31 and 38upwardly by means of link 99.

Formed on the plate BI is a lug I01 which extends inwardly toward theend frame member I2. This lug has rigidly secured to it, a stub shaftI38. Mounted for rotation on this stub shaft is an arm I39 which hasattached to it a hub III. Anothenarm [I2 is also mounted on said shaftand independently rotatable thereon.

This arm is similarly attached to a hub I I3 which rotates on the shaftI08. A torsional spring II4 encircles the two hubs III and II3 and hasone end II5 engaging the arm H2 and the other end III; engaging the armI09. Arm I09 is pivoted by means of a rivet II1 to a link H8. This linkis, in turn, pivoted by means of a rivet II9 to the link 99.

For determining the toasting period, a timing mechanism such asdisclosed in the above mentioned patent is employed. This timing mech-.i'

anism utilizes a strip of bi-metal I which is mounted for slidingmovement in guides IIZI and I22 carried by the plate GI. This strip ofbimetal is constructed with holes I23 arranged to form a rack whichmeshes with a gear segment I24 best shown in Fig. 5. The gear segmentI24. is carried by a plate I25 which has attached to it a hub I25. HubI26 is journaled for rotation on a stub shaft I21 which is attached tothe plate BI. The plate I25 carries a ratchet I28 which engages a pawlI29 pivoted on a pintle I which is also attached to the plate 6|. Thepawl I29 has a finger I32 which rides upon the strip of bi-metal I23. Aheater I33 disposed below the bi-metal I20 causes the same to arch andraise the finger I32. This releases the pawl I23 from engagement withone of the teeth of the ratchet I29. The segment I24 urged by spring II4then causes the bi-metal to travel along the guides HI and I22 until anunheated portion of the bi-metal is opposite the heater I33. Thus, theplate I25 is given a step by step movement depending upon the heating ofsuccessive portions of the strip of bi-metal.

In order to hold the bread racks 31 and 38 in position to cause toastingof the bread, a latch lever I34 is employed. This latch lever is pivotedby means of a rivet I35 to the plate 9| and has an arm I36 extendingoutwardly therefrom. Arm I36 rides on a roller I43 pivoted to the end ofshaft I08. The upper end I31 of the lever 91 constitutes a catch whichis adapted to engage the arm I36. A spring I38 hooked at one end on apin I39 secured to plate 5| and hooked at its other end on a hook I4Iformed on the lever I34 which includes a switch ItiI.

urges the said lever to move in a clockwise direction as viewed in Fig.5. Movement of the said lever is terminated by means of a stop I42formed on the plate 9! and engaging another arm I43 on said lever. Thelever 49 and the lever 91 are operable through a slot I44 formed in theplate 6!. When either of the finger pieces or 56 are depressed, lever 49is swung outwardly. This lever engages the lug I02 on lever 91 andforces the said lever outwardly. The catch I31 has a cam surface I45which engages the arm I36 and raises the same against the action of thespring I38 to permit of moving the catch I31 in back of the said arm.This latches the lever 91 and holds the bread racks 31 and 33 depressedso that the bread resting thereon may be toasted.

For releasing the bread racks 31 and 38 upon completion of the toasting,the arm H2 is employed. This arm has a finger I45 which is adapted toengage a lug E41 bent outwardly from the arm I43 of lever I34. When thearm H2 is swung in a counter-clockwise direction as viewed in Fig. 2,the said finger engages lug I41 and releases the bread racks. Spring I03then rotates shaft 59 and returns the parts to the position shown inFig. 2. The arm I I2 has connected to it a link I43 which, in turn, isconnected to a stud I49 attached to plate I25. As the timing mechanism Coperates, the plate I 25 is moved in a clockwise direction as shown inFig. 5 and the link I43 elevated. This swings the arm II 2 from its fullline position as shown in Fig. 7 to its dotted line position aspreviously described. For the purpose of resetting the timing mechanism,a shoulder I5! is formed on the hub II! which is adapted to engageanother shoulder I52 formed on the hub II3. When the spring I33 rotatesshaft 59, the linkage connected to hub III is operated which rotatessaid hub in a clockwise direction as shown in Fig. 3. Shoulder I5I thendrives hub II3 in the same direction and resets the timing mechanism.

Energization of the heating elements 26 is procured through a heatingcircuit, not shown, This switch is best shown in Fig. 6. Formed on theend case member I5 is a block of insulating material I32 which hasattached to it, two contacts I63 and IE4. Another block I35 ofinsulating material is formed on the said case member in spaced relationto the block I53 and carries a leaf spring I66. Attached to the leafspring I36 is a jumper I61 which serves to close the heating circuitthrough the contacts I63 and M4. The switch I6! is actuated by means ofthe lever 43 which is formed with a cam I58 which engages the leafspring I69 and depresses the same to bring the jumper H51 in contactwith the contacts E53 and I04 when the finger ieces 55 or :5 aredepressed.

In the particular form of the invention shown, a dash pot I53 isutilized which is mounted on the plate 9! by means of a bracket I54.This dash pot includes a cylinder I55 which has a piston I53 movabletherein. Piston has pivotally connected to it, a piston rod I51 whichis, in turn,

ivoted to the plate I25. This construction provides slow movement of thebread racks to ejecting position, thus preventing throwing of the breadout of the toaster and lessening the jar to the device.

The method of operation of the invention is as follows: Depressingfinger piece I5 rotates. lever 49 about shaft 59 in a counter-clockwisedirection as viewed in Fig. 2 to the position shown. in Fig. 3, carryingwith it the arm 16. This arm 7 bears against lug I02 causing arm 91 tomove in unison with arm 49 about shaft 59. The movement of arm 91 istransmitted through link 99 to arm 9| causing said arm to rotate in aclockwise direction about rivet 93. This actuates the straight linemotion 8| which, in turn, causes the bread racks iii and 38 to belowered to their lowermost position in the heating ovens. Link 95 beingconnected to arm 9!, is correspondingly moved upon depression of thefinger piece 15. Motion from this link is transmitted through the link II8 to the arm lilil causing said arm to move in a counter-clockwisedirection about shaft I03. This tensions spring H4 urging arm I [2 tomove in a counter-clockwise direction. Arm H2 being connected by meansof link I48 with the segment i2 l urges the strip of bi-metal iZU tomove through its supports I22 to procure timing of the toaster. Thelatch lever I34, when the finger I is suificiently depressed, engagesthe catch 13? and holds the bread racks in lowered position. Lever 48being connected to the lever 49 by means of link It; is caused to movein a clockwise direction when lever 49 moves in a counter-clockwisedirection. This causes the cam 58 to close the switch lBl. As soon asthe finger piece 15 is released, the timing mechanism functions andtoasting commences. When the strip of bi-metal [2o has transversed itscourse, the finger M6 on arm I I2 engages the latch lever I34 andreleases the bread racks. Spring his now returns the bread racks tonormal position and resets the timing mechanism. At the same time, theswitch it! is opened. If, instead of depressing the finger piece '55,the finger piece 56 is depressed, lever 68 is rotated in a clockwisedirection as shown in Fig. 2 to the position shown in Fig. 3. Lever 48being connected to lever 49 by link i8 causes movement of the lever 49to the same position as it would have moved x had the finger piece i5been depressed. The mechanism connected with lever 59 is then operatedin the same manner as previously described.

The advantages of the invention are manifest.

By means of the instant invention, the toaster can be operated fromeither end of the case and the finger pieces serving to operate thetoaster also serve as handles for carrying the same about. With thepresent construction, most of the parts are pivotally mounted so thatfriction due to sliding is greatly reduced thereby providing aconstruction which will. operate indefinitely without attention. fheoperating parts of the mechanism for lowering the toast from eitherfinger piece is confined within the space between the innermost heatersso that the toaster does not need to be increased in size. Constructionof our toaster is such that heating of the parts does not affect theoperation of the same.
